Kernel.org, the primary site for the Linux kernel source, was compromised sometime in August. It is believed that the attackers gained access using compromised user credentials, and then escalated their privileges to root. Early pieces of information implied that some OpenSSH source code was stored on the compromised Kernel.org server(s), apparently this may not be the case. So far the investigation has found that several modifications were made to the compiled OpenSSH client and server binaries running on the system to log user activity. The full extent of the changes is not yet known, and nobody has yet come forward to claim this hack.

If you’ve installed or updated your kernel or OpenSSH recently, you may want to reinstall from a known good version, although it is not yet known if any kernel sources were modified. Although in this case OpenSSH wasn’t compromised, admins can consider running some form of Single Packet Authorization, such as fwknop, as an additional layer of protection for your SSH server against these kinds of issues (backdoors) and other potential future 0days.

Hopefully more info will come to light as the investigation progresses. Hit the jump for more details.

WordPress.com (the blog hosting platform) was compromised by hackers using an undisclosed vulnerability. My guess is the attackers found an unpatched server somewhere, and used that to get into the environment. Information from Automattic is limited, but they’re assuming that source code and other information was probably stolen. Nobody has come forth to claim the hack, or post WordPress’ source code and account information online, Gawker-style.

If you have a blog on WordPress.com, I recommend changing your password there (and on any other site where you may have used the same password). If you host your own WordPress blog, there isn’t cause for concern just yet as there are many ways that the hackers could have gotten root access, so the vulnerability used may not be within the WordPress software itself.

“Do not meddle in the affairs of hackers, for they are subtle and quick to anger.”

Following last week’s hacking of shamed LIGATT CEO Gregory D Evans, this week it was the turn of security firm HBGary to get exposed. HBGary have been aiding the FBI with their investigations into members of Anonymous. Although Anonymous isn’t a centralised ‘group’, their recent DDoS attacks and hacks of oppressive governments and anti-wikileaks organisations (including PayPal, MasterCard and VISA), have made them a target of the US Federal Government.

HBGary were allegedly preparing to hand over information about certain members of Anonymous to the FBI, who have already made several arrests in the US and UK, and obtained over 40 search warrants in an attempt to shut down Anonymous (probably not possible imo). Angered by CEO Aaron Barr and HBGary’s involvement in FBI investigations, members of Anonymous compromised a number of HBGary servers, defacing their website, gaining access to CEO Aaron Barr’s Twitter account, and obtaining a large number of emails. In what seems to be the popular punishment at the moment, over 50,000 corporate emails were released in a torrent. Anonymous also stated, on one of their many Twitter accounts, that the source code of HBGary’s security products was also obtained – although these don’t appear to have been released (yet?).

“You’ve angered the hive, and now you are being stung.”

Anonymous posted a message to HBGary on their defaced website, where they mock the firm for their lack of security and the unsubstantial ‘public’ information that was going to be handed sold to the FBI.

It appears that the website (rm’d), email and Twitter account of the much disliked LIGATT CEO Gregory D Evans have been hacked, and 84,668 of his emails have been leaked in a 4.15GB torrent. Evans, self-declared “World’s Number 1 Hacker” and also a convicted felon, is frequently outed by many in the security industry for his use of plagiarism, fraud and unethical practices. This leak is probably due to his consistent harassment of security professionals who have been vocal about exposing his activities. A full and descriptive profile of Evans is available at SecurityErrata.org.

Messages were posted on Evans’ hacked Twitter account (above), pointing to a Pastebin (since removed). Here is an excerpt:

Do not meddle in the affairs of hackers, for they are subtle and quick to anger.

When one thinks of frauds in the infosec community, most people are quick to point to Gregory D Evans of LIGATT Security[…]

He’s gone after people at their home to intimidate them and their family. He’s gone after them at their work to discredit them with their employer. And as everyone knows, he recklessly sues anyone who speaks negatively of him on the internet[…]

Enough is enough. He must be stopped by any means necessary. To that end, at the end of this message is a torrent of the inbox of [email protected]

The end of the message contained a link to another pastebin (also removed), which was a Base64-encoded torrent file. The password for the archive in the torrent, as posted on his Twitter feed, is “DoomedCharlatan”. Ligattleaks (now offline), a site dedicated to leaking information about Gregory Evans’ activity (although they say they were not involved in this particular leak), have announced that they will be trawling the emails for evidence of fraud and unethical behaviour.

[Updated] Ligattleaks is back onlineofflineonline offline, for good it seems. Another security firm (HBGary) hacked and exposed for investigating Anonymous.

Every so often I receive an email from someone I know; it talks about something completely random, and almost always includes a link at the end. The same thing sometimes happens on MSN and I get a message like this:

(12:02:36 PM) Friend: Hey! My cat had a spastic fit, and then coughed up a hairball! Check it out!

Now, whether or not that link goes to a malware site, or just someplace for you to buy viagra is not the point. You don’t click on suspicious-looking links… do you?

In some cases they may have simply fallen for a phishing attack, and typed in their credentials where they shouldn’t have. They may even have been hacked due to weak secret questions. More often than not however – and you see this a lot with Hotmail/MSN users – what’s happened is that they logged into their email or MSN on an infected computer, which recorded their credentials. In either of these scenarios the info back to its HQ, where it starts being used to send out spam/viruses/porn/more porn/younameit.

The best solution is to simply change the password (and secret questions) for the account in question. Be a friend, and tell them that they’ve been 0wned.
